MACHINE FOR FORMING SACKS FOR SUSPENSORY BANDAGES.

Specification of Letters Patent.

Patented April 24, 1906.

Application filed August 4.1902. Serial No. 118.395.

To all whom it may concern.-

Be it known that I, JUSTIN KAY Tomas, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Imp rovements in Machines for Forming Sacks for Suspensory Bandages, of which the following is a specification.

My invention consists of a novel machine for shrinking and ironing or setting fabric material, and it has reference particularly to forming sacks for suspensory bandages.

The object of the invention is to provide a machine of simple and inexpensive construction which can be easily operated to set fabric material in a shape designed for some particular use.

In the accompanying drawings I have shown one embodiment of my invention.

Referring to the drawings, Figure 1 is a side elevation, and Fig. 2 is a front elevation, of the machine. Fig. 3 is a transverse sectional view through the irons.

In the drawings like numerals of reference indicate corresponding parts in the several figures, and referring thereto designates a frame of some suitable construction adapted to support the parts of the machine.

11 designates a pair of irons which are eonstructed in the form of hollow steam-chests and carried by the steam-pipes 12. These steam-pipes, which have an asbestos covering 12, enter the irons on opposite sides thereof, as shown in Fig. 3, and extend rearwardly and connect with a main pipe 13, Fig. 2. The irons are provided with flat opposing ironing-faces 14, and drain pipes 15 are connected with the irons to carry off the water of condensation. I prefer to cover the steam-pipes and the outer sides of the irons with asbestos or other suitable material to confine the heat and also protect the operator against burning.

A forming-die 16 is carried by a collar 17, which is arranged to move on a rod 18, secured in the bracket 19, which is fastened to the frame. This rod 18 is mounted at an angle to the vertical and horizontal planes of the machine, so that the formingdie will travel between the irons in an angular direc tion. The die is constructed to correspond to the shape in which it is desired to set the fabric material and is shown in the drawings provided with a curved edge 20 to form sacks for suspe'nsory bandages. The fabric mate rial is cut into blanks of suitable character and fastened on the prong 21 at the toe and on the laterally-projecting prongs 22 at the heel of the die, and the fabric can be stretched as tightly as desired in arrangingit onthe die.

At the bottom of the machine I provide a standard 23, to which a pedal-lever 24; is pivoted, and this pedal-lever engages a pin 25 in the bifurcated die-lever 26, which is also pivoted to the standard 23 at a point below the pivot of the pedallever. The upper end of the dielever 26 is connected by a link 27 and a chain 28 with the collar 17, the chain operating over a pulley 29 on the bracket 19 to facilitate its movement. The die is thus carried in a downward and forward direction in between the irons by depressing the pedal-lever 24, and in order to return it to its upper position I provide a pair of springs 30, which are connected at their lower ends to the lugs 31 on the collar 17 and at their upper ends to the cross-piece 32 on the rod 33, which is arranged at the same angle as the rod 18 and constitutes, in effect, a continuation thereof.

The irons are ad justed to shrink and iron the fabric material on the die as the latter is carried between the ironing-faces, and after the die has reached the downward limit of its movement I provide for clamping the irons tightly against the fabric under considerable pressure to thoroughly shrink and set it in the shape to which it has been drawn. This is accomplished by means of a system of levcrs which is preferably and conveniently constructed in the form of a lazy-tongs 34, which is connected at one end by links 35 to lugs 36 on the irons and at the other end by a link .57 with a lever 38, pivoted to the frame at one end and connected at its other end by a chain 39, which is fastened to a pedal-lever 40. The tongs-lever 38 is normally held in elevated position with the irons separated to the full limit of their movement by means of a spring 41, connected to the outer end of said lever and to the frame.

The arrangement and operation of the parts thus brielly described is such that the die is caused to travel quickly and in an angular direction down between the irons, the latter being adjusted close enough together to iron and shrink the fabric back and up from the lower rounded edge of the former.

In order to set the fabric more quickly and in an effective manner, I prefer to dampen the blank or at least that part thereof which is to be stretched, and to enable the steam to escape from between the irons when they are brought in contact with the dampened fabric I prefer to apply the subsequent pressure of the irons on the fabric and former in a com paratively slow manner, a very high degree of pressure being obtainable, however, by means of the lazy-tongs described. As the die is carried to the limit of its downward movement in between the irons, the latter engage and iron back the fabric and hold it away from the rounded edge thereof, this angular movement of the die being important in order to provide the proper rounded shape for the sack.

It is of course apparent that the construction and arrangement of parts of my invention may be changed and varied in many respects without departing from the spirit thereof, and I reserve the right to make all such changes as fairly fall within the scope of the invention. The die may be changed to shape the fabric in different ways and for different purposes, and if it should be desired to have the die travel between the irons in a ver tical or horizontal plane it would be only necessary to change the pitch of the bracket 19, which could be accomplished by a skilled mechanic. Then the die shown in the draw ingsis used, the fabric is doubled up over the lower edge 20 thereofand on both sides of the die and engaged with the prongs 21 and 22, so that the ironing effect will be produced on the fabric in a direction back from the rounded edge thereof toward the heel of the die, thus shrinking the fabric into the form of a sack, and the subsequent pressing after the former has come to rest at the limit of its downward movement will effectually set the fabric in the shape to which it has been ironed. While I have shown and described a machine'embodying my invention as adapted for making suspensory sacks, it can be adapted with very little alteration for shaping fabric for other purposes and with equally satisfactory results.

I make no claim herein to the method employed in making sacks, as that forms the subject-matter of another application filed by me.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is

1. The combination of a pair of irons having opposing and substantially rectangular ironing-surfaces, and a die carrying material to be operated upon and arranged to travel diagonally between said ironing-surfaces.

2. The combination of a pair of irons having opposing ironing-surfaces, a die carrying the material to be operated upon, and means for moving the die in a downwardly and forwardlydirectionbetweenthe ironing-surfaces.

3. The combination of a pair of irons hav ing opposing ironing-surfaces, a die carrying the material to be operated upon and arranged to travel between the ironing-surfaces in contact therewith, and prongs on the die to engage and hold the material.

4. The combination of a die carrying the material to be operated upon, substantially rectangular-shaped irons for shrinking the material into shape, and means for moving said die in a diagonal direction to and away from said irons.

5.
